The
RDM/DMX protocol combination is fast becoming the first choice for
bi-directional data delivery. DMX-Net RDM modules provide a flexible,
cost efficient distribution method for those protocols. With most
distribution systems, RDM requires that the controller be located only
at one end of the network. If splitters are used, the controller is
connected to the input on the first splitter. The DMX-Net RDM modules
provide a much less restrictive distribution approach. Each of the
modules acts as an RDM hub. Controller placement is flexible because
input modules can be placed at any point on the network.

In many installations DMX-Net RDM allows you to configure a RDM distribution system without
using patch panels or complicated routing switchers. Use DMX-Net RDM
coupled with other technology nodes (like DMX over Ethernet) to
multiply the number of ports at reasonable cost.

DMX-Net RDM*
discourages excessive daisy-chaining, making fault isolation easier,
and time to repair shorter. Instead of one DMX outlet in the FOH slot,
put in four or five; a damaged cable will disable only a few color
scrollers instead of every FOH unit. Install an input and then take
your DMXter4 with you, for easier trouble shooting.

Unlike systems
using passive wall plates, the DMX-Net RDM user doesn’t need to know
the hidden wiring topology. Each output provides a galvanically
isolated RDM controller port with a guaranteed full strength signal.
There are no hidden stubs. No other outlets with unterminated or over
terminated cables to cause reflections. Ground loops are controlled.
Radio frequency grounding is stable, unlike with ad hoc portable
splitters.

The system
consists of two types of RDM port modules, one for input and one for output. They are fitted with Neutrik
connectors and will fit in a single gang box. They are ideal for use in
low voltage chambers of power battens and truss wire ways.

Each module has a bi-color
tally LED. The LED indicates the status of each module - is it powered
and available, is it inputting or outputtng data, or is there a fault
condition.?

Each module is connected by a
two piece screw terminal connector to a private RDM distribution bus.
The bus provides a DMX/RDM pair, power, power common, and shield. All
modules include a terminator for the private bus; the ones at the ends
of the bus are enabled during installation. If required the private bus
may have branches (star topology). This requires adding a branching
module for each branch.

The low cost of the hardware
and installation of DMX-Net RDM will allow more RDM ports, more
flexibility, and greater fault isolation. Even in systems using DMX512
alone, DMX-Net RDM allows the creation of flexible networks that are
impossible to achieve with any standard splitter topology.
